`csmaps` is a package for map visualisation developed by members of CSIDS. The package contains map data for Norway at different levels geographic granularity and layout.

    library(csmaps)
    #> csmaps 2025.8.21

    library(ggplot2)
    library(data.table)
    library(magrittr)

A map with the default layout can be made in this way. For more advanced layout and customization, see the relevant documentation vignettes.

    pd <- copy(csmaps::nor_municip_map_b2024_default_dt)
    q <- ggplot()
    q <- q + geom_polygon(
      data = pd,
      aes(
        x = long,
        y = lat,
        group = group
      ),
      color="black",
      fill="white",
      linewidth = 0.2
    )
    q <- q + theme_void()
    q <- q + coord_quickmap()
    q <- q + labs(title = "Default layout")
    q
